| Abstract: | The computer-aided nanometer roundness measurement system consists of a Talyrond 3 roundness instrument,a precision indexing table and an IBM-PC micro computer. Using multi-step error separation technique, the measurement accuracy of the roundness instrument has been improved from original 25um to 2nm. The method error, system error and its test results are discussed in detail in this paper. The extended application of this technique has great significance for technical reform of our existing roundness instruments. |
